Introduction

Cowork is Anthropic's AI agent for knowledge work. Think of it as Claude Code for everything else. It works autonomously with your computer, local files, and applications to accomplish complex tasks.

This guide walks you through the easiest and most secure way to connect your Bitquery account to Cowork via Composio Connect, enabling it to show real-time Ethereum mempool transactions, count unique wallet addresses for Solana, query historical Bitcoin transactions from 2021, and more such actions on your behalf without compromising your account security.

Also integrate Bitquery with

Connecting Bitquery to Claude Cowork

1. Open Customize

In Claude Desktop, click Customize in the left sidebar, then select Connectors and click the + icon at the top.

2. Add the Composio MCP server

Click Add custom connector and paste in the Composio MCP server URL:

bash
https://connect.composio.dev/mcp
Add custom connector dialog with Composio MCP server URL

3. Authorize in your browser

Click Connect. You'll be redirected to a browser window where you can authorize Composio to continue.

4. Connect your Bitquery account

Back in Cowork, ask the agent to connect to Bitquery or give it any Bitquery-related task.

For example, ask Cowork to:

  • "Show real-time Ethereum mempool transactions"
  • "Count unique wallet addresses for Solana"
  • "Query historical Bitcoin transactions from 2021"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Cowork, and your Bitquery account is ready to use.

What is Claude Cowork?

Claude Cowork is Anthropic's agent for general knowledge work. It can use your computer, files, and connected applications to complete longer-running tasks across your work tools.

With Composio Connect, Cowork can securely access apps like Bitquery through MCP without you sharing account credentials directly with the agent.

What is the Bitquery MCP server, and what's possible with it?

The Bitquery MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Bitquery account. It provides structured and secure access to blockchain datasets and real-time analytics, so your agent can perform actions like querying historical transactions, streaming mempool activity, selecting blockchain networks, and aggregating metrics across 40+ supported chains.

  • Seamless blockchain data querying: Let your agent run powerful queries on historical or real-time blockchain data across multiple networks using Bitquery's combined or archive databases.
  • Live mempool monitoring: Subscribe and stream pending transactions from EVM-compatible chains in real time, enabling instant insights into network activity as it happens.
  • On-demand network and database selection: Have your agent dynamically select blockchain networks and datasets—like Ethereum, BNB Chain, or others—to tailor queries for your specific use case.
  • Metric aggregation and analysis: Automate the aggregation of transaction counts, unique values, or conditional metrics, empowering your agent to analyze blockchain trends without manual intervention.
  • Advanced GraphQL customization: Use aliases and conditional snippets to refine data responses, ensuring clarity and precise control in complex blockchain analytics workflows.

How to build Bitquery MCP Agent with another framework

FAQ

What are the differences in Tool Router MCP and Bitquery MCP?

With a standalone Bitquery MCP server, the agents and LLMs can only access a fixed set of Bitquery tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Bitquery and many other apps based on the task at hand, all through a single MCP endpoint.

Can I use Tool Router MCP with Claude Cowork?

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Bitquery tools.

Can I manage the permissions and scopes for Bitquery while using Tool Router?

Yes, absolutely. You can configure which Bitquery scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Bitquery data and credentials are handled as safely as possible.
